Animating Shapes at Arbitrary Resolution with Non-Uniform Stiffness

摘要: We present a new method for physically animating deformable shapes using finite element models (FEM). Contrary to commonly used methods based on tetrahedra, our elements are the bounding voxels of given shape at arbitrary resolution. This alleviates complexities and limitations tetrahedral volume meshing results in regular, well-conditionned meshes. show how build set masses stiffnesses order model physical properties as accurately possible any Additionally, we extend fast robust tetrahedron-FEM approach case hexahedral elements. permits simulation arbitrarily complex interactive rates manner that takes into account distribution material within
